Book
Books mean knowledge. Even Vegapunk, a genius scientist, agreed with that.
Therefore, Vegapunk viewed the destruction of Ohara's library as a great loss to humanity. He always thought one day he would have the time to visit his friend Clover and enjoy the books of the library. But now, everything was destroyed – the knowledge collected over centuries in books was lost forever.
And his friend dead.
Hence, Vegapunk stood bewildered before a sea filled with the books he thought were forever lost. Maybe he could still learn the secrets of Ohara's library.
– And the reason for his friend's death.
